WASHINGTON — The Democratic Congressional Campaign Committee is expanding its campaign to tie Republican members of Congress to the fiscal cliff, with robocalls to 35 districts.

The new push will echo calls being made by Democrats in Washington, who have publicly pressured Republicans to sign a discharge petition to force a vote on an extension of tax cuts for income less than $250,000.

The calls will also plug the site GOPHostageTakers.com, where the DCCC says 400,000 people have already signed up in support of the Democrats' position.

A recent poll conducted by Pew showed that Democrats might be making headway in the fiscal-cliff messaging war: The preponderance of respondents indicated that they would blame Republicans if the fiscal cliff deadline passes without resolution.
